Galaxy Zoo - Wikipedia

Abstract. We present first results from Galaxy Zoo 2, the second phase of the highly successful Galaxy Zoo project (). Using a volume-limited sample of 13 665 disc galaxies (0.01 < z < 0.06 and M r < -19.38), we study the fraction of galaxies with bars as a function of global galaxy properties like colour, luminosity and bulge prominence. Overall, 29.4 ± 0.5 per cent of galaxies in our sample ...

The P mg likelihoods are generally quite accurate, such that every galaxy in the Galaxy Zoo with P mg ≥ 0.6 has been found to show clear evidence of merging (Darg et al. 2009a). The probability that a galaxy is observed to be undergoing a merger or interaction is approximately uncorrelated with the environment except at scales of r p ∼ 100 ...

Galaxy Zoo

History of Galaxy Zoo. The launch of this new version of Galaxy Zoo, the 4th, comes just a few weeks after the site's 5th birthday. It all started back in July 2007, with a data set made up of a million galaxies imaged by the Sloan Digital Sky Survey, who still provide some of the images in the site today.

Morphology is a powerful indicator of a galaxy's dynamical and merger history. It is strongly correlated with many physical parameters, including mass, star formation history and the distribution of mass. The Galaxy Zoo project collected simple morphological classifications of nearly 900 000 galaxies drawn from the Sloan Digital Sky Survey, contributed by hundreds of thousands of volunteers.

While this skepticism is reasonable, Galaxy Zoo shows that when volunteer contributions are correctly cleaned, debiased, and aggregated, they can produce high-quality results (Lintott et al. 2008). An important trick for getting the crowd to create professional-quality data is redundancy, that is, having the same task performed by many ...

Galaxy Zoo: chiral correlation function of galaxy spins★

Galaxy Zoo is the ﬁrst study of nearby galaxies that contains reliable information about the spiral sense of rotation of galaxy arms for a sizeable number of galaxies. We measure the correlation function of spin chirality (the sense in which galaxies appear to be spinning) of face-on spiral galaxies in angular, real and projected spaces.

We propose a variant of residual networks (ResNets) for galaxy morphology classification. The variant, together with other popular convolutional neural networks (CNNs), are applied to a sample of 28790 galaxy images from Galaxy Zoo 2 dataset, to classify galaxies into five classes, i.e. completely round smooth, in-between smooth (between completely round and cigar-shaped), cigar-shaped …

Galaxy Zoo: passive red spirals - NASA/ADS

We study the spectroscopic properties and environments of red (or passive) spiral galaxies found by the Galaxy Zoo project. By carefully selecting face-on disc-dominated spirals, we construct a sample of truly passive discs (i.e. they are not dust reddened spirals, nor are they dominated by old stellar populations in a bulge). As such, our red spirals represent an interesting set of possible ...
